Abstract
A camera optical lens is provided, including from an object side to an image side: a first lens having positive refractive power; a second lens having negative refractive power; a third lens having positive refractive power; a fourth lens having positive refractive power; and a fifth lens having negative refractive power. The camera optical lens satisfies following conditions: 0.85≤f1/f≤1.10; −3.00≤f2/f≤−1.50; −50.00≤(R5+R6)/(R5−R6)≤−5.00; 1.50≤R7/R8≤3.50; and 0.70≤d7/d8≤1.20. The above camera optical lens may meet design requirements for large aperture, wide angle and ultra-thinness, while maintaining a high imaging quality.
